Anybody know Pontiacs???

Its a 95 Grand prix and lately there has been like a whirring noise coming I think from the left side. The noise comes and goes though so I am having a hard time pinpointing it

It only comes while driving though and seems to go with the speed the car is moving and seems to get quiter when I hit the brakes.

I can't figure this out, the noise is sometimes there and then it will just stop

Any help would be appreciated

Thanks

Same noise while I was wrking on a Grand Prix in Illinios. Turned out to be a wheel bearing on the drivers side front.

cv joints and wheel bearings can both make a whirring sound when in motion, and braked can and do affect the frequency and volume of the sound.

if it didn't vary with braking, i'd say power steering pump. people drive around with those worn out all the time and it's really annoying.

my friend's grand prix was making a funky sound, so we pulled the wheel and found SHATTERED bearings. that was odd.

actually, mine makes a lot of noises. one i think is the motor mount? its a grrrrrrrrrrr...rrrrrrrrrrr when accelerating. but steady speed it quits. ps pump leaks when ever it feels like it. under the floor i can hear what sounds like a plastic bag or an object hitting the cab floor. theres nothing under there... cars a POS. sell it

I'd bet wheel bearing since it stops when you hit the brakes. Check around center of your wheels and see if it looks like there is rust stains on the wheel coming out of the hub. Also if the bearings are bad enough, you can wiggle the wheel around with your hands. If its that bad, its not safe.

Stupid Nissan I had a couple years ago was a bearing eating fool.

Okay just pulled the front tires off I can move the calipers around like they aren't even tight, are they supposed to be able to move like. I have never seen a caliper be able to move around when bolted on and I can't tighten them up anymore

Check your wheel bearings.
